No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

( I consistently supplement with choline, when vegan, because the choline-deficiency is bluntly a kind of chronic-fatigue-syndrome, & I'm fed-up with health-problems. Eating eggs corrects the choline-deficiency, but blocks me from reaching better-quality meditations, which also is aweful/wrong )
the dosages recommended by the pushers of products are consistently waaay too high, whether laundry-detergents or health-supplements. I use less than 1/2 of the scoop-size, when supplementing with the stuff, because I can feel how wrong it makes my biochemistry when taking the amount they want me taking.
always trust your body's healthsense over what the label pushes you to do, & remember that your-biochemistry may well be incompatible with some "fixes" that pushers are profiting from.
Sorry to be cynical, but that's what evidence has convinced me of.
Whether creatine damages kidneys would be dependent on dosage, obviously.
Apparently the doctor claiming it damages kidneys doesn't consider dosage important?
That's as bogus as the supplement-industry's pretense that the same dosage is right for all different sizes of people, of all metabolisms, of all sexes/genders/hormonal-balances: pseudoscience, absolute.
Proper dosages are when you calibrate to units-per-kg-of-.
So, for me, it might be that taking ( 75 / 10 / 4 )g/day of creatine per 75kg of bodyweight, might be right.
Or something like that.
I know from Gershon's book "The Second Brain", that glutamine-supplements FRY the nervous-system of the gut, as nicotene does..
& that'll never get well-known in the supplement-industry, because of how it'd gimp easy-profits..
Some things are just too outside natural-chemistry to do any good ( like chemically-pure glutamine ), & sometimes it's the insane dosages, compared with normal food, that's the problem..
but it isn't logical to claim that there is no safe dosage for creatine, since dosages can go down to infinitesimal: that isn't logical.
There has to be a safe level for it, unless it's intrinsically harmful, in its pure form.
I'm certain that the pushed dosages will harm kidneys, though.
So, seen in that light, yeah: if taking what the pushers want you taking, then yes, that'll probably damage your kidneys.
There's a limit to what they can deal-with..
I knew a guy who'd worked in a hospital, & he told me he 1 time had to watch a patient destroy their own life by overdosing with vitamin-C: they crushed their kidneys from the inside, with stones.
They wouldn't listen, & that was that: they kept overdosing until they died.
Didn't get deemed valid by the megadose-vitamin-C crowd, obviously..
but how could any organ in our body possibly deal with insane quantities of some single-chemical that they aren't evolved-for, you know?
I just looked at PubMed:
https://pubmed.ncbi.nlm.nih.gov/?term=creatine+kidney
& glanced into the 2nd item I saw, & it stated plainly that unless someone has a kidney condition, it's safe, as far as evidence-based-medicine is concerned.
